I believe four hours is the biologically correct amount of time, though it's also proven that a stomach cannot completely digest meat--and that's when it's cooked. Raw meat would likely be a different story, and it would potentially take longer.

There was also a serial killer in the Chicago area, I believe, that cut his victims up and melted them to sludge in his bathtub with hydrochloric acid, then dumped the remains into trash bags and put them out with the garbage. He got away for the longest time, but the smell of the burning carcasses gave him away.

There was also an episode of the crime show NCIS that dealt with a body dumped into a barrel of hydrochloric acid, and that body, while ravaged, was not completely eaten through after 23 hours of exposure to the acid.

Acid is a slow death, something not a lot of folks seem to realize. It's usually exaggerated in cartoons and things like that for comic effect, but hydrochloric is particularly slow and painful. Sure, you can assume that it won't hurt after it eats through your nerve endings, but that's...still a considerable amount of time.

I actually don't treat vore as porn...specifically, i only like safe or clean vore and i don't have any kind of attraction to it outside of the "good" feelings. Idk why, i'm weird like that. But again, this piece isn't porn; it's art (and it's witty, nice and sly all at the same time! again, well done)
